Figure out why so many choose EPS and Polyiso for their projects. Insulate your project at a fraction of the cost
From EPS, Polyiso, Insulation Plates, PTO Plates, Rolls of PTO, and even the screws. We supply it all.
Best Value
When comparing other rigid insulations, EPS is hands down the lowest cost per-dollar. Another way to look at this is that Expanded Polystyrene offers the highest R-Value per dollar over other types of rigid insulation.
Repels Moisture
A study by the Energy Materials Testing Laboratories (EMTL) proved that EPS installed in a well-constructed roof system does not absorb appreciable moisture, even under conditions characteristic of prolonged, cold, damp winters.
What About Spray Foam?
Spray foam requires a much higher cost up front and the slightly higher R-value rarely justifies the price difference.
Easy Installation
You can use nails, screws, glue, or insulation plates to install the EPS on the ceiling and walls yourself. No fancy equipment or expensive installation fees.
Quick Turnaround
We achieve most deliveries within 3-4 weeks of ordering.

A Professional Finish
You can cover the Expanded PolyStyrene with wood panels, OSB, metal, or leave it exposed and keep your space well lit.

Your Choice of a Radiant Foil
The EPS can come either with a clear plastic layer on one side and the radiant foil on the other side, or the foil on both sides.

Custom Sizes Available
We can get any thickness from .5 inch to 40 inch with a variety of heights and widths to suit your project needs.

Customer testimonials
Hear from a few people we have done business with
— Charles and Arrow Co Insulation did a great job getting me my small order of 108 boards. He even delivered it to me. Everything went flawless and I would do business with them again.
— Arrow Co is as professional as they come. I buy a lot of building supplies and I can tell you first hand the norm is to blame others when something unexpected happens. Charles kept me updated every step of the way, and I got my EPS a week earlier than expected.
— Charles is a great guy and will work hard to make sure you get what you order. I buy from him on a regular basis and his stuff always works great in the crawl spaces I work on.
